Abstract
The disclosure relates to a waterproof camera which comprises a switching member for selecting a real focal length photographing mode and a pseudo focal length photographing mode, a recording member for recording a code denoting the pseudo focal length photographing mode to be recorded on a film when the mode is selected, and a waterproof member for preventing water from entering inside the camera. This is capable of producing the print from the film which is equivalent to that obtained when the angle of view is changed at the time of photographing, without enlarging the outside dimensions of the camera body.
Claims28
A waterproof camera comprising:
- means for selecting a real focal length photographing mode and for selecting a pseudo focal length photographing mode that specifies a scope for printing that is narrower than the scope in the real focal length photographing mode;
- means for recording a signal corresponding to the pseudo focal length photographing mode when the pseudo focal length photographing mode is selected;
- and
- waterproof means for preventing water from entering inside the camerA while permitting said means for selecting to be physically manipulated, said waterproof means enclosing an objective lens of the camera so that the focal length of the objective lens cannot be varied through physical manipulation.

An improved waterproof camera of a compact size capable of selectively taking a wide angle picture and a telephoto picture, wherein the improvement comprises:
- means for selecting between first and second modes of photography, the first mode corresponding to real focal length photography for effecting the wide angle picture and the second mode corresponding to pseudo focal length photography for effecting the telephoto picture, wherein movement of an objective lens of the camera for purposes of varying its focal length is not necessary in order to select between the first and second modes of photography;
- means for storing a signal when the second mode is selected, the signal being stored for indicating that a scope narrower than an ordinary scope of a specific frame of the film is to be printed with a greater magnification to form the same size of print as that formed in the first mode;
